Top 5 Proposal Tools for Marketing Agencies
PandaDoc
PandaDoc is the gold standard for marketing agencies with existing CRM infrastructure. Native HubSpot and Salesforce integrations pull contact, deal, and company data directly into proposals — eliminating manual data entry when pitching new retainer clients. Approval workflows let senior account managers or agency owners sign off before anything goes to a client, reducing embarrassing scope errors that marketing agencies are notorious for.
The template library includes campaign proposal templates covering SEO, PPC (Google/Meta), social media management, content marketing, email marketing, and full-service retainer packages — reducing proposal creation from hours to 15 minutes for templated pitches. Interactive pricing tables let clients select ad spend tiers or add-on services (e.g., "add content marketing +$2,500/mo") directly inside the proposal, generating a custom total before signing.
Pros
- Native HubSpot + Salesforce integration
- Approval workflows for multi-stakeholder sign-off
- Interactive pricing tables for service add-ons
- 750+ templates including campaign-specific formats
- Section-level analytics (see which services clients read)
- Bulk send for agency roster / partner outreach
- Stripe integration for retainer payment at signing
- Free plan (up to 5 docs/month) for testing
Cons
- $19–$49/user/month — expensive for 1-2 person shops
- Complex onboarding compared to simpler tools
- Mobile editing is limited
- No built-in project management or time tracking
Better Proposals
Better Proposals is the best-looking proposal tool for marketing agencies that compete on creative presentation. The campaign proposal templates are polished, web-based, and display beautifully on any device — giving marketing agencies a proposal experience that itself demonstrates their design capabilities. Page-level analytics reveal exactly which sections of your proposal clients spent time on, which is gold for understanding which services attract the most interest.
At $19/user/month it undercuts PandaDoc by a significant margin, and the 24/7 live human chat support means you can get help at midnight before a major pitch deadline. HubSpot integration is available, but Salesforce requires the $49/user Business plan (same as PandaDoc's higher tier).
Pros
- Best visual quality — proposals look genuinely premium
- Page-level analytics to see which services clients read
- 24/7 live human chat support (rare in this space)
- HubSpot integration on Starter plan
- Stripe payment at signing
- $19/user/month — 47% cheaper than PandaDoc Business
Cons
- Starter plan limits 5 proposals — too few for active agencies
- Salesforce requires Enterprise plan ($49/user)
- No approval workflows (proposals go directly to client)
- No time tracking or project management
- Fewer templates than PandaDoc (200+ vs 750+)
Qwilr
Qwilr transforms marketing proposals into live, interactive web pages rather than PDF documents. For agencies pitching $10K+ retainers to sophisticated enterprise clients, a Qwilr proposal signals creativity, modernity, and attention to detail before a single meeting. Embedded video capability lets you include a 90-second explainer video of your campaign strategy directly in the proposal. Interactive pricing tables allow clients to select ad spend levels or toggle on additional channels (e.g., "Add YouTube" or "Upgrade to full social management").
The premium positioning comes at a premium cost: $35/user/month (Business) with HubSpot and Salesforce integration only on the Business plan. For smaller agencies, Better Proposals delivers 80% of the design impact at nearly half the price.
Pros
- Stunning web-page proposals — best design in the industry
- Embedded video for campaign strategy walkthroughs
- Interactive pricing tables for service tier selection
- Accept-and-pay in one click on the proposal page
- HubSpot + Salesforce integration (Business plan)
- Strong impression on enterprise clients
Cons
- $35/user/month — most expensive in this comparison
- No free plan (14-day trial only)
- Fewer templates than PandaDoc
- No approval workflows
- ROI harder to justify for sub-$5K retainer pitches
Proposify
Proposify excels at process control for marketing agencies with multiple account managers or business development reps. Content locking prevents junior team members from editing approved service descriptions or pricing tables, ensuring brand consistency across every client pitch. The rep-level analytics dashboard shows which account managers are closing proposals fastest and where in the proposal clients are dropping off — valuable coaching data for agency owners managing a sales team.
At $9/user/month it's significantly cheaper than PandaDoc and Better Proposals, making it attractive for agencies with 5–15 users. Salesforce integration is available but requires the Business plan.
Pros
- Content locking to protect approved service copy
- Rep-level analytics for coaching account managers
- Partner/owner approval workflows
- $9/user/month — most affordable team option
- Salesforce integration (Business plan)
Cons
- Dated UI — feels less polished than competitors
- Template library weaker than PandaDoc
- No built-in invoicing or payment collection
- HubSpot integration lags behind PandaDoc's depth
Bonsai
Bonsai is the right choice for solo marketing consultants or 2-person marketing boutiques who need proposals + contracts + invoicing in one place without managing multiple tools. At $17/month flat, it covers the entire client journey from proposal to retainer billing — including time tracking for hourly or hybrid retainer pricing models. For solo marketing consultants billing $3K–$8K/month retainers, Bonsai delivers excellent value.
The limitation is scale: Bonsai caps at 6 users and lacks the CRM integration and approval workflows that growing marketing agencies need. It's a starting tool, not a long-term agency platform.
Pros
- Proposals + contracts + invoicing + time tracking at $17/mo flat
- Built-in retainer billing for monthly campaign management
- Time tracking for hourly/hybrid pricing models
- Expense tracking for ad spend reporting
- Cheapest all-in-one option in the market
Cons
- Maximum 6 users — not scalable for growing agencies
- No CRM integration (HubSpot/Salesforce)
- Limited template library vs. PandaDoc
- No approval workflows or content locking
- Proposal design quality below Better Proposals/Qwilr

Pricing Guide by Agency Size
Frequently Asked Questions
A complete marketing agency proposal should include: (1) Executive summary — the client's core marketing problem and your proposed solution; (2) Scope of services — detailed breakdown of deliverables (e.g., X blog posts/month, Y keywords targeted, Z ad campaigns managed); (3) Strategy overview — your approach, platforms, and methodology; (4) Pricing — monthly retainer or project-based fees, preferably with interactive tiers; (5) Timeline — onboarding, launch, and reporting cadence; (6) Case studies — relevant results from similar clients; (7) Terms — payment schedule, revision policy, cancellation policy; (8) E-signature and payment collection.
The ideal length depends on deal size. For retainers under $5,000/month: 4–6 pages covering problem, solution, pricing, and social proof. For retainers $5,000–$15,000/month: 8–12 pages adding detailed methodology, case studies, and team bios. For enterprise retainers above $15,000/month: 15–25 pages with full audit findings, phased strategy, detailed deliverables, and risk mitigation. Better Proposals' page analytics consistently show that clients spend the most time on pricing and case study sections regardless of total proposal length.
Web-based proposals consistently outperform PDFs on close rate for marketing agencies. Web proposals allow you to: track which sections clients read (and re-read), embed video walkthroughs of your strategy, include interactive pricing tables where clients can customize their own scope, and enable one-click signing and payment. Both Qwilr and Better Proposals create web-based proposals. PandaDoc supports both formats. Use PDF only when a client's procurement system requires a document attachment.
PandaDoc has the deepest HubSpot integration available — proposals are created directly from HubSpot deal records, contacts auto-populate, deal stage updates when a proposal is viewed or signed, and won deals trigger automations. Better Proposals also integrates with HubSpot from its Starter plan but with less bidirectional sync. If HubSpot is central to your agency's sales process, PandaDoc is the clear choice.
All five tools reviewed here support retainer payment at signing via Stripe, though the implementation varies. PandaDoc, Better Proposals, and Qwilr allow clients to enter payment details and authorize recurring charges within the proposal itself. Proposify uses a Stripe link. Bonsai has the most complete solution — built-in recurring invoicing, automatic retainer billing, and expense tracking in one platform — making it ideal for solo consultants managing the entire financial workflow themselves.
